PAS-C01 Technology Practice Question
A company is migrating its SAP ERP system from on-premises to AWS. The migration involves a heterogeneous database migration from Oracle to SAP HANA. Which AWS service should be used to perform the database migration with minimal downtime?
⚠ Common exam trap
Candidates often confuse AWS SCT (schema conversion) with AWS DMS (data migration), or assume homogeneous migration is sufficient, not realizing that Oracle to SAP HANA is a heterogeneous migration requiring DMS with a specific SAP HANA target endpoint.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Database Migration Service (AWS DMS) with a heterogeneous migration using the SAP HANA target endpoint
AWS DMS supports heterogeneous migrations, including from Oracle to SAP HANA, by using built-in conversion capabilities or integrating with AWS SCT for schema transformation. This allows continuous data replication with minimal downtime, as DMS can perform ongoing changes from the source during the migration window.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Schema Conversion Tool (AWS SCT)
Why it's wrong here
SCT helps convert the database schema but does not perform the data migration.
- ✗
AWS Server Migration Service (SMS)
Why it's wrong here
SMS migrates entire servers as images, not suitable for database schema and data conversion.
- ✓
AWS Database Migration Service (AWS DMS) with a heterogeneous migration using the SAP HANA target endpoint
Why this is correct
DMS supports heterogeneous migrations using the SAP HANA endpoint, allowing schema and data conversion with minimal downtime.
- ✗
AWS Database Migration Service (AWS DMS) with a homogeneous migration
Why it's wrong here
Homogeneous migration is for same database engine; Oracle to HANA is heterogeneous.
